Abstract

L'invention concerne un dispositif électrochirurgical comportant une électrode de découpage allongée déformable. Cette électrode est dotée d'une extrémité distale libre présentant une longueur exposée d'au moins 0,5 pouces, et fixée par son extrémité proximale à l'extrémité distale d'une poignée. Ce dispositif électrochirurgical est conçu pour être utilisé avec un générateur électrochirurgical haute fréquence doté d'une sortie à une fréquence comprise entre environ 1 MHz et environ 10 MHz, de préférence entre environ 3 et environ 8 MHz. De préférence, cette sortie comprend une forme d'onde essentiellement sinusoïdale présentant une distorsion harmonique réduite. Les méthodes associées présentent une incision améliorée de divers tissus, tels que les tissus musculaires, les tissus conjonctifs, les tissus glandulaires et les tissus gras. Ce dispositif convient notamment à la réalisation d'une biopsie du sein.
